Default Looking for (plastic) boxes that come in two same or similar halve to enclose a two inch cube (approx) - ideas?

I'm after some small boxes to enclose some hall effect current sensors
on some large (to me anyway, 1.5cm dia) cables.

The ideal solution would be a box that comes in two equal halves each
about 2" x 2" x 1" such that when the two halves are put together they
enclose a 2" cube. There would of course have to be semicircular
cutouts in the two halves to feed the cable through but I'm quite happy
to cut/grind these myself if I can find suitable boxes.

Can anyone suggest anything suitable? Size isn't all that critical, a
bit bigger won't matter too much. Plastic would be best but metal
boxes would be OK. They don't have to be watertight or anything, this
is low voltage (12 volts) and all I'm after is mechanical protection.

All the boxes from Rapid, RS and Farnell seem to be the type with a
flat lid, as are most 'adaptable boxes'. Not to mention that none of
them are anything like the cube shape I want. Actually almost any box
that's something like a 2" cube would be an improvement on what I've
found so far.

What about a Choc Box?

That's the idea but totally the wrong shape, it's 90 x 50.6 x 28.3mm.
My current sensors are toroids about 40mm diameter (with lugs that make
them bigger) that the wire must feed through so, in the same order as
the dimensions given above, I need NN x 50 x 50mm. NN needs to be
about 50 as well but wouldn't matter if it was a little more.

why not pot them in casting resin?


A bit difficult with a big hole right through the middle for the
cable! If you mean cast a blob onto the cable I suppose that would be
possible but it would be difficult to test and set up before potting
it. .... and anyway I'd still need a box of about the size I
suggested to start with to pour the resin into.

This is *almost* what I want though I'd prefer it a bit smaller and
threading the cables through will be quite difficult I suspect:-

Because it has free-range peroxides running amok during curing and it
will drivel up any electronics nearby.

Pot them in resin by all means, but shell out for the right stuff.

Can't you just pot the whole thing?

Could you remove the innards from cheap water-resistant 13A sockets
and just use the outers - spring close lids and squidgy rubber
grommets

Owain

Make them out of perspex and use silicon to bond the sides together, then
paint whatever colour.

Not deep enough really.

That http://www.maplin.co.uk/potting-boxes-1664 web page is about
typical Maplin standard nowadays too. At the top it lists:-

FD96E - Potting Box cube (£0.89)

But there's no sign of FD96E at the bottom and none of the boxes
there could be described as a 'cube'.

I suspect that an FD96E might be just what I want, but how do I find
out? My local store does have three in stock so I might just go and
take a look.

That's an idea, I have a couple knocking around.
